A335 P22 is a seamless tube made of ferritic alloy stainless steel. Chemically, the alloy of SA335 P22 material contains trace amounts of carbon, manganese, sulfur, silicon and phosphorus. The main additives in the alloy are molybdenum and chromium, which give stainless steel excellent mechanical properties. Tensile strength, corrosion resistance, hardness and other properties are enhanced and improved. Molybdenum reduces the brittleness caused by the addition of chromium.

ASTM A320 Grade L7 is a material specification for bolts, studs, nuts, and other fasteners designed for high temperature bolting applications. ASTM A320 L7 grades are divided into 4 performance classes, A, B, C, and D, each with different tensile and stress rupture properties. Class 660 fasteners are used to bolt boilers, pressure vessels, pipe flanges and valves for high temperature service.

Astm a335 P91 pipe is a seamless pipe for high temperature applications. These pipes are made of ferritic alloy steel. Chemically speaking, a335 P91 welded pipe contains elements such as molybdenum (Mo) and chromium added to the alloy. The tensile strength of sa335 grade P91 pipe increases when molybdenum and chromium are added to the alloy. The tensile strength of a335 grade P91 pipe is 415 Mpa, while its yield strength is 205 Mpa. Pipe elongation ranges from 20% to 30%.

B8M Grade 1 fasteners require carbide solution treatment, while Grade 2 fasteners require additional strain hardening operations to increase strength and reduce susceptibility to wear.

A335 grade P5c pipe is a low alloy carbon steel (Cr-Mo) self-quenching in air where high hardness and residual stress are required for welding and it is not recommended for direct use in services requiring critical conditions. This situation requires the application of post weld heat treatment (PWHT). If you want to avoid PWHT then you can use preheat (120¡ãC) when soldering A335 grade P5c tubes. PWHT is required if the thickness of ASTM A335/ASME SA335 P5c alloy steel pipe is greater than 13 mm.

Alloy Steel Flange Material can differ according to its chemical composition. Low Alloy Steel Flanges are widely used for automotive and aerospace bodies, offshore and onshore structural engineering plates and railway lines.

The alloying elements of A335 also impart higher corrosion resistance to the steel pipe. This also makes it the first choice for chemical companies.

These are said to be specifications for alloy flanges for high pressure and service. The 3% carbon content of these flanges provides a lot of room for improved weldability, which also increases their overall strength.

They are ideal for applications carrying corrosive or high-temperature fluids or gases. Industries that could benefit from chrome moly flanges include: Oil and Gas, Refinery, Power Generation, and Chemical Processing.

We feel proud to introduce ourselves as the well-known manufacturers, exporters and suppliers of Alloy Steel F21 Flanges.

Stainless steel is a versatile alloy is considered to be amongst the most widely used metals across the world.Stainless Steel A403 WP304 contains higher chromium and low carbon content.

Flange connection has good strength and sealing, simple structure and low cost. It can be repeatedly disassembled.

Alloy 20 (Alloy 20) is an iron-based austenitic alloy developed to resist sulfuric acid corrosion. It has excellent resistance to sulfuric acid corrosion; it has strong resistance to phosphoric acid, nitric acid and chloride environments, chloride stress corrosion, pitting corrosion and crack corrosion. Therefore, alloy 20 has the name of anti-corrosion alloy; it has a wide range of applications: such as: chemical, food, medicine, power production and plastics industries will use it. For resistance to pitting corrosion and chloride corrosion, stress corrosion cracking problems, etc., alloy 20 is often used.

Grade B7 is a heat treated chromium molybdenum low alloy steel with a minimum tensile strength requirement of 125 ksi (860 Mpa), a yield strength of 105 ksi (720 Mpa) and a maximum hardness of 35HRC. Boltport produces B7 headed and headless bolts from alloy steel AISI 4140 bar stock or forgings. A193 Grade B7 is the most commonly used bolting size, plus A194 Grade 2H nuts are used for bolting carbon steel pipe. A193 B7 bolts are available in metric sizes from M6 to M180 and imperial sizes from 1/4 to 7 inches in diameter.
